..., a `top`-like tool to show runtime statics of KVM events. An example of what the results look like[1]. - Or use the 'perf' to record nested virtualization related KVM events: $ perf record -a -e kvm:kvm_exit -e kvm:kvm_entry \ -e kvm:kvm_nested_vmexit -e kvm:kvm_nested_vmrun Or the 'perf kvm' utlitiy. See here[2] for more details. [1] https://kashyapc.fedorapeople.org/virt/kvm_stat-VMCS-Shadowing/kvm_stat-L0-VMCS-Shadowing-enabled.txt [2] http://www.linux-kvm.org/page/Perf_events -- /kashyap

Hi all, I got a new laptop recently and what worked before no longer works (Fedora 23 on the laptops in both cases)... I'm trying to get nested virtualization to work because I use the VMs on the laptop to simulate an HA cluster that itself hosts VMs. I don't care much at all about the performance of the nested VM, it's just there so that I can work on the cluster's code.
